CAMAS, WA (January  26, 2022) – The PLEXSYS Utilities Team is pleased to announce the Direct Link Interface (DLI) 6.8 software release. DLI is a hardware and software solution for customers with a requirement to interface operational data link terminals and live participants with virtual or constructive participants in a simulated virtual world.

Highlights include:

  • Flexible protocol translation tool that allows different platforms to exchange data.
  • Provides simulators and real-world operational systems with the ability to exchange multiple data link message standards in real-time, including Link 16, Link 11, AIS, CIB, UDL, and more.
  • Going beyond data link, adapts simulation to inject sensor reports into operations software.
  • Performs Link 16 gateway role, routing Link 16 messages between a distributed interactive simulation (DIS) network and external interfaces such as MIL-STD-3011 Joint Range Extension Applications Protocol (JREAP) and Standardization Agreement (STANAG) 5602 Standard Interface for Multiple Platform Link Evaluation (SIMPLE).
  • Performs DIS gateway role, routing DIS messages between two or more DIS networks.

Release focus:

This software release focused primarily on DIS filtering improvements for DLI. The advances better position DLI for the DIS gateway role. Changes included:

  • Ability to limit notifications from DLI plugins
  • Added ability to allow filtering for specific DIS entity IDs
  • Added ability to filter PDUs used for voice radio modeling

“DLI is developed from the ground up with the customer in mind,” stated Davor Braut, Product Manager. “Customer operational system is the star of the show, DLI quietly maximizes training by connecting it to simulation.”
